Functions used in UFOextender's new interception routines

For those that might want to know how accuracy is calculated with the new options for interception turned on:

X-Craft Accuracy

[(1+((3-(.5*(difficulty level-1)))/UFOsize)/2 ] * Weapon Accuracy ....... [beginner=1..superhuman=5]

Diff	Ship Size				
	VS	S	M	L	VL
begin	0.8	0.875	1	1.25	2
exp	0.75	0.8125	0.91667	1.125	1.75
vet	0.7	0.75	0.83333	1	1.5
Genius	0.65	0.6875	0.75	0.875	1.25
Super	0.6	0.625	0.66667	0.75	1
         

UFO Accuracy

60 + ((difficulty level-1)*3) - [Cautious Mode bonus (10)]

Decompiled accuracy algorithm?

Hi Morgan/Tycho

Is the algorithm you describe above, what you have decompiled from the standard game? Or is it a variant for UFOExtender? Great news if you have decompiled what the game actually uses - I will need to check some of my firepower calculations to make sure they are still in line with the algorithm.

It is an extender version of the original formula if one chooses to enable it. The original formula is the one that has been noted already: [(1+(3/UFOsize))/2 ] * Weapon Accuracy ... UFO sizes going from 5 for very small to 1 for very large. If one were to set the extender's interception difficulty to beginner, the algorithm's output is the same as the original one. The original UFO accuracy algorithm is a flat 60% chance to hit despite difficulty level. Morgan525 19:23, 30 June 2012 (EDT)
